A tip about summer dormancy in cyclamen:
Cyclamen never go entirely dormant, and when planted out, their roots are very far-ranging. Even during summer dormancy, their roots continue to imbibe moisture and the tubers therefore remain turgid. This is why dried off cyclamen tubers in bags are so badly shrivelled and need such care to re-hydrate and return to active growth. Overwatered, they'll simply rot in their weakened state.
Cyclamen in pots therefore do better with a trace of moisture available. One technique is to use very tall pots, and sit them in a few mm of water so there is always moisture at the deepest levels of the pot. Another method is to plunge pots in a bed of sand which you water from time to time.
Young cyclamen seedlings are especially prone to dying from desiccation, hence are in particular need of summer water.
It is also advisable to keep your cyclamen pots shaded from the side so the soil does not overheat during the summer.
